Vampire Dragons are members of the undead. They sustain themselves by drinking the blood of others. It is said that they are only “alive” at night, and seem dead or asleep during the day, as they cannot endure sunlight for long periods of time. Vampire Dragons can only reproduce by changing the eggs of other dragons, puncturing the shell with their fangs and injecting venom that kills the baby inside.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Heaven's Gatekeeper is a young female Vampire dragon. She was accepted into the Vampire clan run by Salasas, and she is very fond of the male. She now helps Salasas run the clan, and has also helped in raising the frozen female hatchling, Blood of Dragonkin. Heaven's Gatekeeper spends most of her time hunting with Salasas. When she's not doing that she helps Blood of Dragonkin care for the Vampire hatchlings.
